Ribosome

[raibәsәum]

解释:

(noun.) an organelle in the cytoplasm of a living cell; they attach to mRNA and move down it one codon at a time and then stop until tRNA brings the required amino acid; when it reaches a stop codon it falls apart and releases the completed protein molecule for use by the cell; 'the ribosome is the site of protein synthesis'.
